ABSTRACT: The Buck converter with LC input filter operating in
discontinuous output current mode has a high power factor with a constant duty
cycle. A Buck converter in this operation mode can reduce the reverse recovery
loss of the freewheeling diode thus increase the efficiency. The operation,
power factor analysis and modeling of the converter are studied in this paper.
Experimental results are presented to verify the theoretical predictions.
